However, it should be mentioned that in those days, there was no merit system thus a statement that buying a ranked-up account is not true.
I just don't know how you can tell that lie to our face and expect us to swallow it. Not because of the supposed year of purchase, but because you evidently bought a ranked-up account, a full member account.
At that time there were ranks but no merits, and you bought a full member account that had ranked up based on activity and time since registration basically. That's assuming you bought it when you say so, which I find quite unlikely.
Maybe with your manager you will be lucky and you can continue in the campaign with the tags. And I'm not saying this because it's him specifically, because nowadays one or two red tags doesn't automatically mean that you get kicked out of the campaign. However, as you accumulate more, the probability that you will be able to stay in the campaign decreases.
